UNITED STATES PATENT OFFICE.

MACHINE FOR IRONING FOLD-COLLARS.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed June 8, 1906. SBTiEl N0- 320,777.

To all whom it may concern:

Be it known that I, Lnwrs R. HEIM, a citizen of the United States,residing in Danbury, Fairfield county, Connecticut, have inventedcertain new and useful Improvements in Machinesfor Ironing Fold-Collars,ofwhich the following is a specification.

This invention relates to the class of machines of which that describedin my United States Patent No. 818,247, dated April 17, 1906, is a type,and wherein a machine for shaping the collars is provided with arotating ironer for the folded edge of the collar, to operate as thelatter emerges from the rolls of the machine; and the present inventionmay be considered as an improvement on said machine, many parts of thepresent machine being substantially the same as those shown in myaforesaid patent.

The purpose and objects of the present improvements will be betterunderstood after a description of the construction and operation of themachine shall have been given. y 1

In the accompanying drawings, which illustrate an embodiment of theinventionFigure 1 is a plan of stantially at line 0: in Fig. .1. Fig. 3is a vertical section taken at line x in Fig. 1. Fig. 4 is an undersideview,'with the legs in horizontal section and one of the gear-wheelsbroken away. The remaining views are details. Figs. 5 and 6 are sectionviews of the mechanism for driving the rotating ironer. Figs. 7 and 8are detail views of the rotating ironer and the supporting rollers for acollar, C shown therein.

According to the present invention, 1 designates the bed or support,mounted on or provided with suitable legs.

2 is the driving-shaft, mounted rotatively in bearings below the bed. 3is the driving pulley on said shaft.

4, 4, are two upright rollers, adapted to be driven from the main shaft2 through means to be hereinafter About the rollers 4, .4, is a belt,band or apron 5, which takes about an upright tightening roller 6,mounted on an arm 7, which swings about a post 8 on the bed and has atorsion spring 9, which tends to swing the arm and roller outward in amanner to tighten the belt 5.

10 is an upright non-yielding roller which holds the belt 5 up to therollers 4, 4, as seen in Fig. 1.

A standard 11, mounted on the base, receives the folded collar, whichpasses under a grooved wheel or roller 12, and thence to the rollers 4,4, and 10. A grooved wheel, or roller 13 disposed adjacent to the pointwhere the collar emerges, rolls upon and irons the fold of the collar.

So far as above described the elementary features are the same as thoseillustrated in my aforesaid patent.

Fig.2 is a vertical section taken sub The features wherein theconstructive differences reside, will now be described.

In the present construction the upright rollers 4, 4, are rotativelymounted each by a journal at its lower end, in one arm of an elbow-lever14, fulcrumed at 15 on the underside of the machine bed; and the otherarm of saidlever is cushioned against a spring 16 (Fig. 4) backed by atension-regulating screw 17. The functionof the springs 16 is to keepthe rollers 4 pressed in toward each other yieldingly, the degreesofpressure being regulated by the screws 17 The upright pressure roller10 is rotatable in a long bearing on the underside of the bed and it hasno other motion. On the lower ends of the respective rollers 4, 4, aresecured gear-wheels 18, and these gear with a wheel 19 on the long,pendent journal of the pressure roller 10; and this roller is driventhrough the medium of a worm-wheel 20 on the journal of the roller 10,which gears with a screw 21 on the main shaft 2.

In my former patent the roller corresponding to the saddle-roller 12herein, is positively driven, but in the present case it is not.

A gas-pipe 22 serves to heat the roller 10, and wheel 13. Broadly suchheating devices and features are not new.

An important novel feature of the invention will now be described.Disposed adjacent to the outlet where the collar emerges from therollers 4, 4, are two upright supporting rollers 23 and 24 (Fig. 3).Both of these rollers are slightly coned or tapered at the top, thetapered portion extending down for about fiveeighths of an inch on thefull-sized machine; the body of the roller 23 tapers downward and thebody of the roller 24 is cylindrical. The roller 23 is driven throughgear-wheels 25 and 26, respectively, on the lower end of the journal ofsaid roller 23 and on the journal of the roller 10. The roller 23 drivesthe roller 24 through gear-wheels 29. The function of these rollers isto support the collar while its folded edge is being pressed upon andironed by the grooved wheel 13, and in order that the rollers may nipthe folded collar at a point a little way below its fold and thus avoidcracking or breaking the material of the collar at the fold, the rollersare coned or tapered a little at the top. The roller 23 is tapered belowin order to make room for the flare of the outer fold of the collar, theinner fold of the latter being upright, the roller 24 is madecylindrical and forms a guide for the collar as it emerges. The rollers23 and 24 will have a peripheral speed equal to or a very little lessthan the surface speed of the belt or apron 5, so as not to destroy theshape given the collar by the rollers 4, 4 and 10.

In order to cause the rollers 23 and 24 to grip the collar with ayielding pressure, and to provide for varying this pressure, the roller23 (see Fig. 4) is carried by one arm of an elbow-lever 30, fulcrumed at31, so that the said roller may have a little movement laterally towardand from the roller 24; and the other arm of said carrying lever isbacked by a spring 32, which is in turn backed by a tension-regulatingscrew 33.

The wheel 13 (see Figs. 5 and 6) is fixed on a hori zontal shaft 34,rotatively mounted in a bearing-piece 35, which is provided with asleeve that slips down over an upright, bearing-piece 36, mounted on themachine-bed. An upright shaft 37 extends up through the bearing-piece36, and on the upper end of this shaft is a spiral gear 38, whichengages, for driving, a gear 39 on the horizontal shaft 34. On the lowerend of the shaft 37 is a pinion or gear-wheel 40 (Fig. 2) which gearswith a spur wheel 41 on the journal of the roller 10. It is necessarythat the grooved ironing-wheel 13 shall press with some force on thecollar, and it is found that the rollers 4, 4, and 10 cannot always berelied on to so support the emerging collar as to resist this pressure;and moreover, when the last end of the collar fold emerges from the biteof the rollers 4, 4 and 10, its support therefrom is lost just at thetime when the ironer 13 is most needed to iron that part of the foldededge near the tab of the collar. The rollers 23 and 24 supply thissupport. By observation of Figs. 2 and 7 it will be seen that a verticalplane passing through the axes of the rollers 23 and 24 is somewhatnearer the rollers 4, 4 than is a vertical plane passing through theaxis of the wheel 13.

Preferably there will be a guide-piece 42 disposed between the roller 4and the adjacent roller 23, and fixed to the machine-bed. Thisguide-piece is merely to insure the emerging end of the collar passingin between the supporting rollers. The wheel 13 will have a peripheralspeed slightly greater than the speed at which the collar is moving; andit may have a slight vertical adjustment, as explained in my formerpatent, without disengaging the driving gears. The means employed hereinfor this purpose is substantially the same as that shown in my formerpatent.

It will be noted that in the present case the upright 'roller 10 is notmovable laterally, as in my aforesaid patent, and that the lateralmovement required is in the rollers 4, 4. The object in this is to guidethe collar properly to the bite of the rollers 23 and 24. This featurecould not be attained properly if the roller 10 were laterally movable.

It may be explained with reference to the detail views, Figs. 7 and S,that they show a fold collar 0 gripped between the rollers 23 and 24 atthe point indicated by the dotted line 2.

The present invention is not restricted to means for supporting thecollar under the edge-ironer, constructed precisely as herein shown,although this construction is preferred.

Having thus described my invention, I claim' 1. A machine for thepurpose specified, having a mechanism for shaping and feeding thecollar, means for guiding the collar into said mechanism, an independentironer, adjacent to the outlet. of said mechanism and so disposed as toiron the fold of the emerging shaped collar as it emerges from saidmechanism, and means situated under the ironer for supporting the movingcollar while its folded edge is being finished by said ironer.
